I can mount qcow2 img to nbd devices through guestfish or qemu-nbd I'm curious about which performance is better?

The architecture of

I followed the http://libguestfs.org/guestfs-building.1.html to build source. git clone https://github.com/libguestfs/libguestfs cd libguestfs ./autogen.sh make I installed the lib I didn't have it and everything is ok untill I enter *make* I got error message: > CCLD libguestfs.la > ar: `u' modifier ignored since `D' is the default (see `U') > make[3]:

guestfish --listen necessarily redirects its stdout to /dev/null so as not to interfere with eval. The remote protocol doesn't contain any other provision for collecting stdout for the caller, so executing guestfish --remote will never generate any output. This patch fixes that by forwarding the caller's STDOUT to the listener over the unix socket connection. The listener redirects its

I think calling "sh" before "mount" should not confuse guestfish like that: # guestfish (1.20.4 on sles11sp3) Welcome to guestfish, the libguestfs filesystem interactive shell for editing virtual machine filesystems. Type: 'help' for help on commands 'man' to read the manual 'quit' to quit the shell ><fs> add-drive

OK, subject says using guestmount. I'm surprised the slowdown isn't more than 95%. It's using FUSE which goes through an insane number of layers,

Nearly any program that writes to standard output can benefit from this sort of fix. Without it, running e.g., ./guestfish --version > /dev/full would exit successfully, even though it got ENOSPC when writing to the full device. That means regular output redirected to a file on a full partition may also fail to be written, and the error ignored. Before: $ guestfish --version >

Is "luks-format" supposed to work with guestfish? Like guestfish <<EOF luks-format /dev/sda4 0 EOF Appearently it lacks an option to give the passphrase programmatically. Was this option skipped on purpose? Olaf

I download libguestfs from github and fetch to the *origin master*. I tried to build libguestfs in my own linux distro and I followd the http://libguestfs.org/guestfs-building.1.html#using-a-prebuilt-binary-appliance to replace with supermin I download the appliance-1.30.1.tar.xz and appliance-1.30.1.tar.xz.sig and extract the tarball to /home/user/appliance and export

I come across this page libguestfs.org/guestfs-performance.1.html <http://libguestfs.org/guestfs-performance.1.html> This raises my interest. I am currently learning how to benchmark performance qemu. So here is my questions: 1. Can I use guestfish or any tools provided by libguestfs to benchmark qemu? How? (The command I use below is correct or what's the correct command to execute

While creating my first guestfish script I noticed an inconsistency in the guestfish(1) man page. The option tgz-out references "tar_out", which does not exist, instead its called "tar-out". The same is true for tgz-in/tar_in. After a quick grep in the code its not clear to me how to resolve this issue. Olaf

This no going to work. AS I told you I need something under guestfish command list not from guestfs commands.
